What SA law requires

Written contract

Domestic building work must be in a written contract complying with Part 5 of the Act.

Cannot contract out

Parties cannot contract out of Part 5 protections. Any attempt to waive statutory rights is void.

Required contract contents

Must include:

• Names and addresses of parties
• Description of the building work
• Contract price
• Payment schedule (progress payments)
• Date for commencement
• Date for completion (or method for estimating)
• Details of prime cost and provisional sum items

Statutory warranties

Implied into every domestic building work contract:

• Work performed in a proper and workmanlike manner
• Work performed in accordance with all statutory requirements
• Work performed with reasonable diligence (if no completion date specified)
• Work performed with suitable materials
• Work resulting in a home reasonably fit for occupation

Critical: proceedings for breach of statutory warranty must be commenced within 5 years of completion. This period cannot be extended — one of the strictest limits in Australia.

Building indemnity insurance

Required for domestic building work above certain thresholds. Verify insurance before paying a deposit.
